Hairpiece

ABSTRACT

The present invention relates to a band-type hairpiece. Nipping parts are formed through pressing in an upper resilient side of a base frame of a wig clip, and at the same time, a tip of each of the nipping parts is constructed to be caught by two adjacent knots of sewing thread with which strands of false hair are sewn. Thus, the amount of resilient steel sheet consumed for fabricating a wig clip is reduced and the wig clip is prevented from coming out from the false hair. Alternatively, roll-fitting parts are formed through pressing in an upper resilient side of a base frame of a wig clip, and an end of a bundle of false hair of the roll-type hairpiece, which is fixed using an adhesive, is fixedly fitted into each of the roll-fitting parts. Thus, an operation for connecting the roll-type hairpiece to user&#39;s hair is simplified and a user who intends to use a roll-type hairpiece can fix the roll-type hairpiece to his/her own hair by himself/herself, whereby he/she can connect the roll-type hairpiece to his/her hair without going to a beauty salon or receiving help from other people.

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a hairpiece used for a partial wig, and more particularly, to a hairpiece which can be constructed to be easily attached and detached and also be easily manufactured at low production costs.

2. Description of the Prior Art

Generally, hairpieces are roughly classified into band-type hairpieces and roll-type hairpieces according to their shape.

Band-type hairpieces are made in the form of a band by arranging a plurality of strands of false hair chemically processed and tying them with sewing thread using a sewing machine while forming knots at predetermined intervals. Portions thereof tied with the sewing thread form an attachment end that will be attached to a user's head. The attachment end may be lined with a wig base made of cloth by means of sewing thread using a sewing machine.

On the other hand, roll-type hairpieces are made in the form of a roll by extracting a bundle of false hair chemically processed, arranging the false hair with respective ends thereof aligned with one another, and fixing the ends using an adhesive.

In band-type hairpieces, strands of false hair are cut to a predetermined length by a worker and a clip is attached thereto. To attach the clip to the hairpiece in the prior art, attachment holes are formed at both lateral ends of the clip which in turn is sewed on the attachment end of the hairpiece or the wig base in such a manner that the worker manually passes thread through the attachment holes one by one. Thus, there are problems of cumbersome work and lowered productivity.

To solve these problems, Japanese Patent Laid-Open Publication No. 2001-329422 (published on Nov. 27, 2001) discloses a wig clip and a wig with the clip, wherein nipping parts 3 are formed to protrude from a lower resilient side 22 of two opposite longitudinal resilient sides 21 and 22 of a base frame 2 of a wig clip 1 and to be inserted between wig bases 6 and 7 and a nipped portion 8 installed inside of the wig bases 6 and 7.

When it is intended to fix the wig clip 1 to user's hair, a user holds and presses both sides of the wig clip 1 with his/her both hands such that a plurality of hair-fixing pins 4 are spread while being spaced apart from the lower resilient side 22. Thereafter, distal ends of the plurality of hair-fixing pins 4 are caused to be slid from above to below the user's hair so that strands of hair are fitted between the hair-fixing pins 4, and the wig clip 1 is then pressed in an opposite direction. Then, the distal ends of the hair-fixing pins 4 between which the user's strands of hair are fitted are brought into contact with the lower resilient side 22 and the hair-fixing pins 4 come together so that the user's strands of hair are fixed therebetween.

Here, one of the two longitudinal opposite resilient sides 21 and 22 of the base frame 2 of the wig clip 1, which forms a base end of the hair-fixing pins 4, is referred to as an upper resilient side 21, whereas the other of the resilient sides with which the distal ends of the hair-fixing pins 4 are in contact is referred to as the lower resilient side 22.

However, since the nipping parts 3 of the wig clip disclosed in Japanese Patent Laid-Open Publication No. 2001-329422 protrude from the lower resilient side 22 of the base frame 2 and are then bent by 180 degrees to extend toward the upper resilient side, there is a problem in that upon pressing a resilient steel sheet to fabricate one wig clip 1, the amount of resilient steel sheet consumed increases in proportion to the lengths of the elongated nipping parts 3.

Moreover, since the nipping parts 3 of the wig clip disclosed in Japanese Patent Laid-Open Publication No. 2001-329422 have simply sharp tips 3 a, there is a problem in that if a wig is inadvertently pulled in a direction in which the nipping parts 3 extend, the nipping parts 3 come out from the wig bases 6 and 7 and thus the wig clip 1 comes out from the wig. To prevent this, in the wig clip disclosed in Japanese Patent Laid-Open Publication No. 2001-329422, auxiliary nipping parts 5 protrude from the upper resilient sides 21 of the base frame 2 of the wig clip 1 and are then bent by 180 degrees to extend toward the lower resilient side. However, in order for a worker to fit the auxiliary nipping parts 5 into the wig bases 6 and 7 in a state where the nipping parts 3 have been fitted into the wig bases 6 and 7, the user should unfold the auxiliary nipping parts 5 by 90 degrees, fit them into the wig bases 6 and 7 and fold the auxiliary nipping parts 5 again. Thus, the work is cumbersome. Further, there is a problem in that upon pressing a resilient steel sheet to fabricate one wig clip 1, the amount of resilient steel sheet consumed greatly increases in proportion to the lengths of the elongated auxiliary nipping parts 5 in addition to the lengths of the elongated nipping parts 3.

Meanwhile, as for the roll-type hairpiece, ends of bundles of false hair secured using an adhesive are fixed to user's hair. In the prior art, as disclosed in U.S. Pat. No. 5,107,867, false hair is fixed to user's hair using a thermally shrinkable tube 30. A plastically deformable ring made of tin has been also used instead of such a thermally shrinkable tube. However, the use of the thermally shrinkable tube or tin ring has a problem in that both user's hair and false hair of the roll-type hairpiece should be fitted into a small hole of the thermally shrinkable tube or tin ring, leading to cumbersome work. Thus, there is a problem in that a user who intends to use the roll-type hairpiece cannot fix the roll-type hairpiece to his/her own hair by himself/herself and should go to a beauty salon or receive help from other people.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, preferred embodiments of a hairpiece according to the present invention will be described with reference to the accompanying drawings.

A band-type hairpiece of an embodiment of the present invention is shown in FIGS. 1 to 7.

As shown in FIGS. 5 and 6, a plurality of strands of false hair 1 chemically processed are aligned with one another and then tied with sewing thread 3 using a sewing machine while knots 5 are formed at predetermined intervals, whereby an attachment end 7 is formed and the shape of a band is obtained.

FIG. 1 shows a wig clip 100 to be attached to the attachment end 7 of the false hair 1.

Referring to FIG. 1, the wig clip 100 comprises opposite longitudinal upper and lower resilient sides 103 and 105 of a base frame 101, both lateral resilient sides 104 and 106 between the upper and lower resilient sides 103 and 105, and a hair-fixing pin 107.

The wig clip 100 attached to the attachment end 7 of the false hair 1 is connected to user's hair.

In the embodiment shown in FIG. 1, in the upper resilient side 103 of the opposite longitudinal upper and lower resilient sides 103 and 105 of the base frame 101 of the wig clip 100, which is formed with a base end of the hair-fixing pin 107, a plurality of nipping parts 109 with sharp tips 111 are formed through pressing at predetermined intervals in the longitudinal direction of the upper resilient side 103.

Such nipping parts 109 are formed through pressing such that portions except their base ends are cut to be spaced apart from the upper resilient side 103.

Here, the nipping parts 109 are formed such that their tips 111 are directed to the top of the upper resilient side 103.

A slant catching step 111 a is formed at any one of both sides of the tip of each nipping part 109. As can be well seen from FIGS. 6 and 7, such a slant catching step 111 a is sized to penetrate between two adjacent knots 5 and be caught by the two knots 5.

That is, it is preferred that a ratio of the maximum width of the tip 111 including the slant catching step 111 a to spacing between two adjacent knots 5 be 1.1˜1.3:1.

If the maximum width of the tip 111 including the slant catching step 111 a is equal to or slightly greater than the spacing between two adjacent knots 5, when the catching step 111 a of the nipping part 109 is fitted between the two adjacent knots 5, the spacing between the knots 5 is instantaneously increased due to the maximum width of the tip 111 larger than the spacing of the two knots 5 and the catching step 111 a passes between the two knots 5. After the catching step 111 a of the nipping part 109 has passed between the two knots 5, the spacing between the knots 5 is decreased so that the catching step 111 a of the nipping part 109 can be caught by the two knots 5.

Since the catching step 111 a of the nipping part 109 fitted into the attachment end 7 of the false hair 1 is caught by the two adjacent knots 5, the nipping part 109 is prevented from coming out from the attachment end 7 of the false hair 1.

A shown in FIG. 2, the portion of the nipping part 109 except its base end can be formed through pressing to be at a certain angle with respect to the upper resilient side 103.

Meanwhile, as shown in FIG. 3, the portion of the nipping part 109 except its base end may be formed through pressing such that a section thereof adjacent to the based end is rounded to be horizontal with respect to the upper resilient side 103.

Although FIG. 1 shows that the tip 111 including the slant catching steps 111 a is in the form of an arrow with protrusions at both sides thereof, the tip 111 including the slant catching step 111 a may be in the form of a barb with a protrusion at one side thereof as shown in FIG. 4.

A roll-type hairpiece according to another embodiment of the present invention is shown in FIGS. 8 to 14.

As shown in FIG. 8, a plurality of false hair 1 chemically processed are extracted on a bundle basis and their ends are aligned and fixed with an adhesive to be in the form of a roll.

FIG. 8 shows a wig clip 200 to which an end 1 a of the bundle of false hair 1 is fixed.

Referring to FIG. 8, the wig clip 200 comprises opposite longitudinal upper and lower resilient sides 203 and 205 of a base frame 201, both lateral resilient sides 204 and 206 between the upper and lower resilient sides 203 and 205, and a hair-fixing pin 207.

The wig clip 200 allows the end 1 a of the bundle of the false hair 1 to be fixed thereto and then be connected to user's hair.

In the embodiment shown in FIG. 8, in the upper resilient side 203 of the opposite longitudinal upper and lower resilient sides 203 and 205 of the base frame 201 of the wig clip 200, which is formed with a base end of the hair-fixing pin 207, a plurality of roll-fitting parts 209 with semi-circular cross sections are formed through pressing at predetermined intervals in the longitudinal direction of the upper resilient side 203.

Such roll-fitting parts 209 are formed through pressing such that portions except their base ends are cut to be spaced apart from the upper resilient side 203.

Here, the roll-fitting parts 209 are formed such that their trailing ends are oriented in the longitudinal direction of the upper resilient sides 203.

FIGS. 9 and 10 show the process of fixing the end 1 a of the bundle of false hair 1 to one of the roll-fitting parts 209.

The end 1 a of the bundle of false hair 1 is fitted into the roll-fitting part 209 shown in FIG. 9, and the roll-fitting part 209 is then pressed. At this time, the roll-fitting part 209 is crushed to fix the end 1 a of the bundle of false hair 1, as shown in FIG. 10.

FIGS. 11 to 14 show another variation of the roll-type hairpiece, wherein a holding bar is installed on an upper resilient side of a wig clip.

In the variation shown in FIG. 11, the wig clip 300 comprises opposite longitudinal upper and lower resilient sides 303 and 305 of a base frame 301, both lateral resilient sides 304 and 306 between the upper and lower resilient sides 303 and 305, and a hair-fixing pin 307.

In the variation shown in FIG. 11, in the upper resilient side 303 of the opposite longitudinal upper and lower resilient sides 303 and 305 of the base frame 301 of the wig clip 300, which is formed with a base end of the hair-fixing pin 307, a plurality of roll-fitting recesses 309 with trapezoidal cross sections are formed through pressing at predetermined intervals in the longitudinal direction of the upper resilient side 303.

The holding bar 310 is installed through revetting on the upper resilient side 303 to be in close contact therewith.

Further, the holding bar 310 is formed with a plurality of bosses 311 with M-shaped cross sections at positions corresponding to the plurality of roll-fitting recesses 309.

Here, the roll-fitting recesses 309 and the bosses 311 are formed to be oriented in a width direction of the upper resilient side 303.

FIGS. 12 to 14 show the process of fixing the ends 1 a of the bundles of false hair 1 between the roll-fitting recesses 309 and the bosses 311.

The upper resilient side 303 is raised from the state shown in FIG. 12 to define a space between the roll-fitting recesses 309 and the bosses 311 as shown in FIG. 13. The ends 1 a of the bundles of false hairs 1 are then interposed between the roll-fitting recesses 309 and the bosses 311, respectively. Thereafter, the upper resilient side 303 is pressed down to fix the ends 1 a of the bundles of false hair 1 between the roll-fitting recesses 309 and the bosses 311.

FIGS. 15 to 17 show a further variation of the present invention.

Although FIGS. 15 to 17 are illustrated by way of example in connection with the wig clip 100 of the embodiment of FIG. 1, it will be understood that the structure shown in FIGS. 15 to 17 can be equally applied to the wig clips 200 and 300 shown in FIGS. 8 and 11, respectively.

In the variation of FIG. 15, outwardly protruding pieces 113 are formed integrally with and at intermediate portions of lateral resilient sides 104 and 106 between the opposite longitudinal upper and lower resilient sides 103 and 105 of the base frame 101 of the wig clip 100.

One of the protruding pieces 113 is formed with a through-hole 113 a at the center thereof, whereas the other of the protruding pieces 113 is formed with a spherical protrusion 113 b at the center thereof.

As shown in FIGS. 16 and 17, a protrusion 113 b of one wig clip 100 is press-fitted into a through-hole 113 a of another wig clip 100′ so that the two wig clips 100 and 100′ can be connected to each other.

According to a band-type hairpiece of the present invention described above, nipping parts are formed through pressing in an upper resilient side of a base frame of a wig clip, and at the same time, a tip of each of the nipping parts is constructed to be caught by two adjacent knots of sewing thread with which strands of false hair are sewn. Thus, the amount of resilient steel sheet consumed for fabricating a wig clip is reduced and the wig clip is prevented from coming out from the false hair.

Further, according to a roll-type hairpiece of the present invention, roll-fitting parts are formed through pressing in an upper resilient side of a base frame of a wig clip, and an end of a bundle of false hair of the roll-type hairpiece, which is fixed using an adhesive, is fixedly fitted into each of the roll-fitting parts. Thus, an operation for connecting the roll-type hairpiece to user's hair is simplified and a user who intends to use a roll-type hairpiece can fix the roll-type hairpiece to his/her own hair by himself/herself, whereby he/she can connect the roll-type hairpiece to his/her hair without going to a beauty salon or receiving help from other people.
